CHURN.

SPECIFICATION forming part of Letters Patent No. 306,4:65, dated October14-, 1884-.

Application filed February 26, 1884. (No modeli) T0 aZZ whom it mayconcern.-

Be it known that I, JOHN BRADBURN, of

-useful improvements in churns, by means of which a better result isobtained than is had by the use of eh urns as ordinarily constructed.

The invention consists in the peculiar construction of its parts andtheir combination, as more fully hereinafter described and claimed.

Figure 1 is a front View, with the churnbody broken away. Fig. 2 is aside view; Fig. 3, a section on the line .1? a; of Fig. 1, and Fig. 4 adetail of one of the fastening devices.

In the accompanying drawings, which form a part of this specification, Arepresents the cylindrical body of a churn, upon the outer wall ofwhich, and near the top on opposite sides, there are secured the loopsa, and on another side is secured an car, to.

IE is a three-armed standard-frame, provided with lugs 11, two of whichare designed to engage with the loops, and thereby secure the standardto the body of the churn, and one of said lugs is slotted to receive thecar a, and is provided with a hole, b, through which and a correspondinghole in the car a a pin may be passed to lock the frame in position. Atthe the center of this standard it is provided with hollow bearings 0,vertical to each other, as shown. This frame, it will be noticed, is00111- posed of the arms B, from one of which rises the overhangingbracket B from which eX- tends the arm B", forming a bearing for theshaft 0. The other arms B extend at right angles to the one carrying theoverhanging bracket, and from each of these arms 13 there extendsdownwardly the arms 7%, and near their lower ends these arms I) areprovided with brace-bars Z), running parallel with the arms B, anduniting at the center of the standard to form a hollow bearing, 0, forthe shaft H, near the center of its length.

In churns of this class, as heretofore constructed, there has been butone short bearing for the lower pinion. This has been found to be veryobjectionable, for the reason that the bearing being so short it soonwears away and the pinion wabbles around. This difficulty is overcome bythe use of my frame B, by means of which I furnish two bearings for theshaft H, which steadies the same and prevents the pinion from wabbling.

O is a crank-shaft, upon which is secured the driving-wheel D, avertical shaft, E, carryin g at its lower on d the dasher-wheel F, whichis made in the form of a three-bladed propeller wheel.

Stepped within the hollow bearings c are the the hubs of the pinions G,which engage with the driving-wheel and give motion to the shaft E andthe dasher-wheel attached thereto in one direction, and to the hollowshaft H, to which the arms I are secured, in the opposite direction. Acollar, (Z, and set-screw 0, above the upper hollow bearing, allows thevertical shaft E, which is inclosed in the shaft H, to be verticallyadjusted independent of the arms I, as maybe required for the differentquantities of cream operated on at diiferent times. No such verticaladjustment is required for the shaft H, as its arms are of sufficientlength to obviate the necessity of any change. The circumference of thedasher-wheel being less than theinternal diameter of the churn-bodyleaves room for the arms of the shaft H to pass between the body anddasher-wheel, and prevents any portion of the cream from be comingstagnant outside the said wheel.

I am aware of Patents Nos. 88,016 and 150,734, and make no claim to theconstruction shown therein as forming part of my invcntion.

I am also aware of the Patent No. 276,290, for an egg-beater, granted toG. Schrebler, April 24, 1883, and make no claim to the constructionshown therein as forming part of my invention.

Vhat I claim as my invention is 1.
